Finding GCD of 72, 42, 93 using LCM Formula
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(72, 42) = 504
GCD(72, 42) = ( 72 x 42 ) / 504
GCD(72, 42) = 3024 / 504
GCD(72, 42) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 93
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 93) = 186
GCD(6, 93) = ( 6 x 93 ) / 186
GCD(6, 93) = 558 / 186
GCD(6, 93) = 3
GCD of 72, 42, 93 is 3
